Thanks, gdl. I got it from these guys in town: http://www.fathertimeantiques.com. Great folks to work with - they are true watch geeks but very patient with a "newbie" (the guy who sold me the watch spent 15 minutes explaining how a mechanical watch works, using a laminated exploding diagram).
I love these stories and seeing people getting 'converted' to mechanical movements. These things are fascinating.
PS: nice selectin but their prices are off-the-charts expensive!!
